本文提出了两种石英空芯微结构光纤(负曲率光纤和光子带隙光纤)，在2.94μm波长下的损耗分别为0.06dB/m和1.1dB/m。这是一种重要的医疗应用，特别是外科手术，因为水在3μm附近存在一个强吸收峰。已经证明了分别为195mJ和14.4mJ的高能脉冲的引导作用。这些能量足以消融软硬的生物组织。作为验证，猪骨在空气中被烧蚀，在水中被浸泡，以模拟手术装置的实际应用。这些光纤为高能Er：YAG激光辐射的新的、完全灵活的传输系统开辟了道路。
In this paper two silica hollow core microstructured fibres (Negative Curvature Fibre and Photonic Bandgap Fibre) are presented with attenuations of 0.06 dB/m and 1.1 dB/m at 2.94 μm wavelengths, respectively. This is an important regime for medical applications, specifically surgery due to the existence of a strong absorption peak for water around 3 μm. The guidance of high energy pulses of the order of 195 mJ and 14.4 mJ respectively has been demonstrated. These energies are sufficient to ablate soft and hard biological tissues. As verification porcine bone was ablated in air and submerged in water to simulate practical application of a surgical device. These fibres open the way to a new and fully flexible delivery system for high energy Er:YAG laser radiation.
